AASHTO T 107M/T 107-17 PDF Download

The AASHTO T 107M/T 107-17 standard provides a procedure for determining the autoclave expansion of hydraulic cement. The test is conducted on a neat cement specimen.

The standard allows for the use of either SI units or inch-pound units and states that the values in each system should be regarded separately as the standard. It notes that the values may not be exact equivalents, and therefore, each system should be used independently. Combining values from the two systems could lead to nonconformance with the standard.

This standard is important for evaluating the expansion properties of Portland cement, which is a critical factor in ensuring the durability and performance of concrete structures. Autoclave expansion tests can help identify potential issues with cement that may lead to cracking and deterioration over time.
